| Abstract | CuO–NiO nanocomposites with high surface areas, which are used as anode materials for lithium-ion batteries (LIBs), are successfully prepared by a facile wet-chemical method. The CuO microspheres, NiO nanosheets and CuO–NiO nanocomposites were characterised by nitrogen adsorption, X-ray diffraction, scanning electron microscopy, transmission electron microscopy and thermogravimetric analysis. The CuO–NiO nanocomposites composed of CuO microspheres and NiO nanosheets possess a high surface area of 158.0 m2 g−1. When the CuO–NiO nanocomposites are used as anode materials, they show an initial discharge and charge capacity of 886.7 and 638.8 mAh g−1. A high capacity of 562.5 mAh g−1 at 0.1 C was observed after 50 cycles, which is higher than CuO (345.9 mAh g−1 at 0.1 C after 50 cycles) and NiO (334.4 mAh g−1 at 0.1 C after 50 cycles), demonstrating that the CuO–NiO nanocomposites with high surface area show a better cycling performance than pure CuO and NiO. Therefore the CuO–NiO nanocomposites materials have a great potential application in LIBs. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
